Modern SM-rated oils have come a long way in lubrication technology, and basically any oil will do your engine justice... unless you beat on it.
I think the poster is referring to the recent controversy surrounding Mobil 1's supposed formulation change. While in the past M1 was a solid performer due to its mostly Group IV PAO base stock, it is said that the new formulation uses less of it and as a result is less robust than it used to be.
Again, these are internet rumors that echo around, without much info to support it. Even if it is true, the reformulated M1 is plenty for most people. Also, it should be noted that superior base stocks do not automatically guarantee a higher quality oil, since the balance of additives has a large impact on an oil's performance. It is entirely possible that XOM has lessened the PAO content of M1 but made the oil better overall through the proper balancing of additives.
That said, I use Amsoil 0W-30 and I'm hoping to increase my interval to 8,000mi or more, as substantiated by future oil analyses. Though I have faith in Amsoil products, I'm not sure if I believe the advertised claim of 17,500mi intervals under severe service.
35,000mi intervals under normal service, they say. Right. Even with an EaO filter, it's kinda hard not to be skeptical. I'll be posting UOAs at BITOG under the same username, keep an eye out.
